dt-bindings: display: convert samsung,s6e63m0 to DT Schema 



The binding for this panel is a SPI slave.

v2:
  - Drop use of spi-slave (Maxime)
  - Introude unevaluatedProperties (Maxime)
  - Drop reg entry in example (Rob)

Samsung s6e63m0 AMOLED LCD panel



Required properties:

  - compatible: "samsung,s6e63m0"

  - reset-gpios: GPIO spec for reset pin

  - vdd3-supply: VDD regulator

  - vci-supply: VCI regulator



The panel must obey rules for SPI slave device specified in document [1].



The device node can contain one 'port' child node with one child

'endpoint' node, according to the bindings defined in [2]. This

node should describe panel's video bus.

Example:



		s6e63m0: display@0 {

			compatible = "samsung,s6e63m0";

			reg = <0>;

			reset-gpio = <&mp05 5 1>;

			vdd3-supply = <&ldo12_reg>;

			vci-supply = <&ldo11_reg>;

			spi-max-frequency = <1200000>;



			port {

				lcd_ep: endpoint {

					remote-endpoint = <&fimd_ep>;

				};

			};

		};
